The system automatically sends out low-credit alert once your credits reach a certain threshold depending on your plan.
For monthly and annual plan subscribers, you will start receiving the alert once you have used up 50% of your subscription credits. And you will get it more frequently once you have less than 100 credits left in your account.
For Pay-as-you-go subscribers, the system starts sending out alerts once you have less than 100 credits left in your account.
To make sure that you get the email, please add
firstname.lastname@example.org to your contact list so the alert is not marked as spam.
